一、電池片回收有什么作用

1、減少對環境的污染壓力

如今，隨著社會經濟的發展，社會環境正面臨嚴峻的考驗。一方面，不可生資源的數量正在減少。另一方面，一些污染現象還在不斷破壞環境的平衡結構。比如說部分人隨意丟棄廢舊的電池片。這種情況(kuang)下，會對環境(jing)的土壤、水(shui)源等產生嚴重危(wei)害。

2、提高資源的使用效率

廢(fei)舊電(dian)池片并不(bu)是(shi)沒有用(yong)途，其(qi)實，廢(fei)舊電(dian)池片可(ke)(ke)(ke)以被再(zai)次(ci)利用(yong)，從而可(ke)(ke)(ke)以提(ti)高資源的使用(yong)效率，尤(you)其(qi)是(shi)一些不(bu)可(ke)(ke)(ke)再(zai)利用(yong)的資源能夠(gou)得到較好(hao)的保護，既能夠(gou)延長資源的使用(yong)時限，還能降低部(bu)分物資對環(huan)境造成的污染。

3、節省了一定的生產成本

從電(dian)池(chi)片(pian)回收公司了(le)解到(dao)，他們使用(yong)廢舊電(dian)池(chi)為原料(liao)，生產新(xin)的電(dian)池(chi)成本得到(dao)了(le)大幅度(du)降低，實現了(le)“雙贏”的局面。

在日常的(de)工作生活中，建議大家要(yao)妥善處(chu)理好廢(fei)舊(jiu)電池片(pian)(pian)，尤其是不(bu)能(neng)隨意處(chu)置，比如說(shuo)丟棄在垃圾堆里，那樣將會造成很大的(de)危害，盡可能(neng)將廢(fei)舊(jiu)電池片(pian)(pian)收集起來送(song)到電池片(pian)(pian)回收公司，在實現廢(fei)舊(jiu)電池片(pian)(pian)回收的(de)同時，對保護環境起到了很好的(de)作用。

三、太陽能電池片怎么進行回收

電池片可以回(hui)收，可以從太(tai)陽能(neng)電池中回(hui)收純硅。

太陽能電池主要含有硅（約91.6%重量）。它還包含其他材料，例如底層的鋁，頂層的銀電極，以及頂層的鉛和抗反射涂層。p型和n型硅晶片位于抗反射涂層和鋁層之間。太陽能電池片藍色層是(shi)抗反射涂層（SiNx），白(bai)線是(shi)銀電極(ji)。太陽能(neng)電池片的底部為(wei)鋁層。為(wei)了去除這些材料（鋁、銀、鉛和抗反射涂層），需(xu)使用化學處(chu)理方法。

首先，氫(qing)氟酸(suan)或氫(qing)氟酸(suan)與其他化(hua)學品的(de)(de)混合物用于去除太陽能電池的(de)(de)抗(kang)反射(she)涂層、銀、鉛和(he)pn結。由于氫(qing)氟酸(suan)是劇毒(du)和(he)腐蝕性化(hua)學品，因此(ci)在目前(qian)的(de)(de)工作中不再(zai)使(shi)用氫(qing)氟酸(suan)。每(mei)一層都使(shi)用化(hua)學處理一層一層地去除。

用濃NaOH溶(rong)(rong)液(ye)(ye)處理(li)(li)(li)(li)后去除(chu)鋁層。在反(fan)應過程中(zhong)形成的氫(qing)(qing)氣被(bei)收集在一個腔室中(zhong)并(bing)可用作燃料。通過過濾(lv)從NaOH溶(rong)(rong)液(ye)(ye)中(zhong)分(fen)離氫(qing)(qing)氧(yang)(yang)化(hua)鋁。類似(si)地，通過用HNO3處理(li)(li)(li)(li)去除(chu)銀(yin)和鉛(qian)。收集釋(shi)放的NO2并(bing)可用于生(sheng)產硝(xiao)酸。分(fen)離硝(xiao)酸銀(yin)，溶(rong)(rong)液(ye)(ye)用HCl處理(li)(li)(li)(li)，形成氯(lv)化(hua)銀(yin)。濾(lv)出(chu)沉(chen)淀(dian)的氯(lv)化(hua)銀(yin)。此外，將溶(rong)(rong)液(ye)(ye)用NaOH處理(li)(li)(li)(li)以從溶(rong)(rong)液(ye)(ye)中(zhong)分(fen)離鉛(qian)化(hua)合物（PbO）。氧(yang)(yang)化(hua)鉛(qian)轉化(hua)為(wei)氫(qing)(qing)氧(yang)(yang)化(hua)鉛(qian)，過濾(lv)沉(chen)淀(dian)的氫(qing)(qing)氧(yang)(yang)化(hua)鉛(qian)。
